**Forecast consensus from multiple meteorological sources places Paris's peak temperature on August 23, 2026, at 24–25°C under partly cloudy to overcast skies with northeasterly winds.** This aligns directly with the market's strong weighting toward 24°C (53.5% implied probability) and 25°C (42.0%), reflecting trader assessment of near-normal late-August conditions. Official forecasts, including those drawing on GFS model output, project a daytime maximum near the long-term average high of ~24.5–24.7°C, with morning lows around 15–16°C rising steadily through the afternoon. Dry air, moderate humidity (declining through the day), and light-to-moderate winds limit both intensification and cooling, keeping readings in a narrow band. Historical data for the date show typical highs clustered around this range, with rare extremes well outside current model guidance. No significant synoptic shifts—such as stronger advection, cloud cover changes, or frontal passages—are indicated in the latest runs, supporting the tight clustering of outcomes. Minor model or observational differences between stations could tip the official daily maximum (typically sourced from Météo-France) between 24°C and 25°C, explaining the near-even split in market-implied odds while assigning negligible probability to 23°C or 26°C+ scenarios.
